Schaue mir zur Zeit das Java3D-Tutorial von Michael Pfeiffer an. Stecke jetzt bei einem Beispiel mit einem KeyEvent fest. Scheinabr reagiert es nicht auf Eingaben. Normalerweise sollte man sich mit den Pfeiltasten drehen und bewegen können.
Der Code ist Original vom Autor des Tutorials , Package habe ich bei mir eingebaut.
Kann mir jemand sagen, ob´s an mir liegt (Tastatur), oder am obigen Code?
Dom.
